Abstract
The invention discloses a special grinding aid for coal-series hard kaolin. The special grinding aid comprises coal ash, cerous nitrate, graphite powder with the fineness of 200 meshes and sodium hexametaphosphate. A preparation process comprises the steps as follows: firstly, the coal ash and the cerous nitrate are mixed uniformly and placed into a calcining furnace to be calcined at the temperature in a range of 800 DEG C-850 DEG C for 1 h, then a calcined material which is taken out of the furnace and cooled is mixed with the graphite powder with the fineness of 200 meshes and the sodium hexametaphosphate and ground in a ball mill for 20-60 min, and grinding bodies in the ball mill are made of non-metallic materials. With the adoption of the special grinding aid, the power consumption of a dry fine powder grinding section of the coal-series hard kaolin is reduced by 5%-8.5%; and the special grinding aid has the characteristics of convenience in storage and usage and lower cost.
Description
Technical field
The present invention relates to a kind of grinding aid special for coal-measure hard kaolin, refer in particular in coal-measure hard kaolin " wet-dry change combination " production technique, be exclusively used in the grinding aid of dry regrind mill workshop section.
Background technology
In current domestic coal-measure hard kaolin production process, the basic technological process of production adopting " wet-dry change combination ", dry regrind mill workshop section is an important cellular manufacture process; In total power consumption of coal-measure hard kaolin product, the current consumption of dry regrind mill workshop section accounts for more than 35% of total power consumption, the mill efficiency therefore by making used additives improve dry regrind mill, and reduction power consumption is an important R&D direction.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of grinding aid special for the dry regrind mill workshop section of coal-measure hard kaolin, this grinding aid special is by flyash, cerous nitrate, 200 order Graphite Powder 99s, Sodium hexametaphosphate 99, through calcining, grinding, compound is formulated, and addition during use is 0.5% ~ 0.8% of abrasive material doses.
The technical problem to be solved in the present invention is realized by following scheme: for the grinding aid special of the dry regrind mill workshop section of coal-measure hard kaolin, it is characterized in that, the each component of composition grinding aid special is flyash 91% ~ 97% by weight percentage, cerous nitrate 0.5% ~ 1.5%, 200 order Graphite Powder 99s 2% ~ 6%, Sodium hexametaphosphate 99 0.5% ~ 1.5%; Preparation process is as follows, quantitatively take in proportion after flyash and cerous nitrate mix and put into calcining furnace in 800 DEG C ~ 850 DEG C calcinings 1 hour, to come out of the stove cooled calcining material and the 200 order Graphite Powder 99s quantitatively to take in proportion, Sodium hexametaphosphate 99 mixed grinding 20 ~ 60 minutes in ball mill, in ball mill, grinding element must adopt non-metallic material, packs the grinding aid special be for coal-measure hard kaolin after going out ball mill.
Advantage of the present invention is the use of grinding aid special, makes the power consumption of the dry regrind mill workshop section of coal-measure hard kaolin reduce 5% ~ 8.5%, and it is easy to use that this grinding aid special also has storage, lower-cost feature.
